The book "Tony Bingelis On Engines" has plans to make your own templets and baffles. That is how I made mine for my 0-235 C1B. Check AS or Amazon. I purchased his book several years ago for less than ten dollars on Amazon. I believe Van's used to sell a templet, but not sure if they still do
Does it show dimesnions for the baffling? I know how baffling is to work, im just looking for sizing to fit the zenith cowling. Thanks
It gives you a scaled drawing that will work with the 0-235. I took poster paper laid out a 1" grid and drew the different parts. I then fitted the poster board on the actual engine to make sure they fit. Then I transferred the templet to .020 6060 T6 and cut the parts out and installed. A little time consuming, but it was less than 50 bucks for book, & aluminum
You know after I saw a completely enclosed baffling, instead of webbing around the edges using the cowl to seal the top of the engine, I simply bent an aluminum top and completely sealed the engine. Only took a couple of hours. Again I used poster paper large enough to cove the entire top of the engine ,marked a line around the baffling, bent a 1/2" flange and cut, notched as necessary for a nice clean fit. Then transferring it to aluminum. It is in stalled on my 601 and the cowling fits just fine.
Yea i like that setup. A little easier than trying to match up the baffle seal as tight fitting as possible. No i have a dynafocal mount already, thanks though.
I figured i might modify a typical airbox. Great, who doesnt love some fiberglass work, ha.
